Hello everyone out there, hope everyone is as excited as I am to get out on their sleds and start rip'n up the powder as I am.
But before I am able to get out there I am asking for some help from anyone who knows more about working on and performing the work on there sleds than I do. The beginning of last winter I purchased a 2020 Polaris XCR 800 from a lady who had purchased I it brand new. I asked her and her husband what or if they had any service done to the machine before and after the season had started and finished. Which they replied no, because she barely used it. It only had 1500 kilometres not miles because I live in Canada that is the setting it was in. So last week I was doing some routine maintenance to it, and decided that I should be cleaning the exhaust valves. So after a bit of a struggle to remove them from the block I cleaned them up really good put new rubber gaskets on them and reinstalled them. Now my issue is that I had to losen the cable in 2 different locations in order to get the assembly out of the block. The big jam nut that sits in front of the I am assuming some sort of valve that is attached to the body of the sled and the nut on the outside of the assembly that moves the valves in and out of the assembly that I am assuming is in sync with the throttle assembly. I asked at the dealer when purchasing the gasket how to go about the removal and the mechanic said to not touch the cable assembly because I would mess up the synchronizing of the valves and would be a big problem if it wasn't put back the way it was before taking it apart. But I had no choice but to losen these nuts in order for me to remove the assembly. Now that I have everything back together I am afraid to try starting it up due to the fact that on a 600 RMK I used to own I had never cleaned the exhaust valves and it was very clear after taking apart the motor exactly why the piston failed. You could see on the end of the valve were it hit the top of the piston because there was a piece missing on it and the top of the piston was damaged right where the exhaust port is. So I would greatly appreciate it if anyone has any thoughts, opinions or suggestions on what I can do or should do about this.. Before I try starting it up only to have it blow up on me haha. Like I said I am not a professional engine mechanic, I am learning as I go so again I thank you for any help I can get
